Planning a tropical getaway means understanding local climate patterns before booking flights and hotels. Puerto Vallarta weather features a distinct tropical wet and dry climate, split between a sun-drenched dry season and a lush, dramatic green season. Knowing what to expect month by month helps you match your travel goals with the right dates, avoid common packing mistakes, and make the most of your time on Banderas Bay.
The region experiences two primary seasonal shifts driven by ocean currents and the Sierra Madre mountains. The dry season spans from November through May, bringing clear blue skies, lower humidity, and steady tourist crowds. The green season runs from June through October, characterized by higher humidity, warmer ocean temperatures, and dramatic late-afternoon thunderstorms that leave the jungle vibrant and alive.
The Dry Season Breakdown: November to May
Travelers seeking guaranteed sunshine and minimal rainfall typically book their trips during the dry season. This period is divided into the festive peak winter months and the comfortable shoulder months.
Peak Winter Months: December to February
Winter brings some of the most comfortable weather of the year. Daytime highs hover around 78°F to 80°F (25°C to 27°C), while nighttime lows drop to a refreshing 64°F to 65°F (18°C to 19°C).
- Rainfall: Practically nonexistent. You can leave the rain jacket at home.
- Crowds: High season brings maximum resort occupancy, higher accommodation rates, and bustling beaches. Booking months in advance is essential.
- Special Highlights: Humpback whales migrate down from colder northern waters into the warm bay during these exact months, making boat tours exceptionally popular.
Spring Shoulder Months: March to May
As winter fades, temperatures gradually climb. March and April are exceptionally dry, often recording zero measurable rainfall. By May, daytime highs reach around 83°F (28°C) and humidity begins a subtle upward creep.
- Ocean Conditions: Water temperatures start warming up, moving from the mid-70s into the high 70s.
- Vibe: Crowds thin out significantly after Easter week (Semana Santa), offering a quieter window to enjoy coastal towns before summer arrives.
The Green Season Breakdown: June to October
Often mislabeled simply as the "rainy season," the green season is a dynamic period that offers incredible value, dramatic landscapes, and fewer tourists.
Understanding Summer Rains
Rain doesn't mean all-day washouts. Typically, mornings and early afternoons remain bright and sunny. Heavy tropical downpours, accompanied by lightning and thunder, develop rapidly in the late afternoon or evening. These storms usually blow over within an hour or two, cooling the air and leaving behind fresh evening breezes.
- Temperature and Humidity: Daytime highs consistently reach 85°F (29°C) or higher, paired with high tropical humidity that makes it feel much warmer.
- Peak Wet Months: August and September record the highest rainfall totals of the year, driven by regional tropical weather patterns.
Why Travel During the Green Season
Budget-conscious travelers and photography enthusiasts find immense value during these months. Resorts and tour operators drop their prices substantially. Furthermore, the daily rain transforms the nearby Sierra Madre foothills from dry brush into a striking, neon-green jungle. Sea turtles also hatch along the beaches during this timeframe, adding unique wildlife viewing opportunities. According to climate records from the National Meteorological Service of Mexico, summer tropical activity requires keeping an eye on regional updates, though direct hurricane strikes remain rare.

Strategic Packing for Your Trip
Packing effectively depends entirely on which season you choose. Bringing the wrong items leads to unnecessary discomfort.
What to Pack for the Dry Season
- Lightweight Layers: Breathable linens and cottons keep you cool during warm daytime excursions.
- A Light Sweater or Jacket: Evening breezes off the ocean and cooler mountain air drop nighttime temperatures enough that you'll want a light layer after dark.
- Sun Protection: High UV indices require reliable sunglasses, wide-brimmed hats, and reef-safe sunscreen. Check guidelines from the Environmental Protection Agency regarding UV safety to protect your skin properly.
What to Pack for the Green Season
- Rain Gear: A compact travel umbrella or a lightweight, breathable rain shell is mandatory for afternoon downpours.
- Quick-Dry Fabrics: High humidity means clothes take longer to air-dry. Synthetic or athletic blends perform much better than heavy denim or thick cotton.
- Insect Repellent: Mosquitoes and other bugs become more active in the jungle environment after heavy rains. Pack an effective bug spray containing DEET or picaridin.
Frequently Asked Questions
Are hurricanes common in Puerto Vallarta?
Major direct hurricane strikes are historically rare. The Sierra Madre mountains and the southward-facing curve of Banderas Bay help deflect or weaken major tropical systems. While heavy tropical storms occur during peak green season months, devastating landfalls happen infrequently.
Is the ocean warm enough for swimming year-round?
Yes. Ocean temperatures range from a refreshing 75°F (24°C) in late winter up to a bath-like 86°F (30°C) in August and September. Swimming is comfortable during every month of the year, though afternoon wave action can occasionally make ocean entry choppy during stormy summer days.
Does it rain all day during the rainy season?
Almost never. Traditional all-day rain washouts are rare in this part of Mexico. Most precipitation arrives in intense, localized bursts during the late afternoon or overnight hours, leaving plenty of morning hours for outdoor activities, dining, and sightseeing.
When is the best time to visit to avoid crowds?
If you want to dodge peak crowds while still enjoying good weather, target the shoulder months of November or late April through May. Alternatively, traveling in June or October offers sparse crowds and deeply discounted resort rates, provided you don't mind brief afternoon storms.
